I've just restored a 1960 Porsche Type 678/4 engine (4-cyl, based on the 356 sports car engine), so now I'm looking to move up to a late-1980s Porsche PFM3200 (6-cyl, 911-based) unit. They were used in about 50 Mooneys, and the PAA pulled the type certificate in April, so if you see one, please let me know.
